BUTT FOR SAND RAMMERS.

Specification of Letters Patent.

Patented May 16, 1922.

Application filed August 2, 1920. Serial No. 4.005199.

To all whom it may concern."

Hammers, of which the following is a specification.

My invention relates to improvements in rammers such as sand rammers andhas more particular relation to the lmtt of such tool and method ofmaking the same. The object thercoi? is to provide a butt of simple andlight construction and one which is moreover very efiicient and durableconsidering the character of the Work done.

In the d a'wings Fig. 1 is an elevation oi a sand rammer butt embodyingmy invention; Fig. 2 asection on the line 2-2 of Fig. 1; Fig. 3 a viewillustrating the mode of operation of producing the butt; Fig. 4 a planview of the die; and Fig. 5 a plan view of the metal disk in itsoriginal shape as used in the die.

Referring to the present embodiment of my invention as herein shown thebutt comprises a body portion 1 which in practice is made very light andconsequently I prefer to employ aluminum as the material and make thesame hollow thereby providing a large central chamber 2. This bodycylindrical at its lower or outer end and is truncated coni cal at itsupper end with the result that there no chance of lodgment of sand uponany portion thereof which would be liable to be thrown back in the faceof the operator dur ingthe ramming operation.

Inasmuch light material such. as aluminum is comparatively soft and notsufficient ly durable to withstand the impact of the butt against sand,etc., I provide the body with an end cap of hard material. such as thinsheet steel which is applied thereto in the following novel manner.

Tlhe extreme lower or outer end of the butt slightly reduced in diameteras compared with the main body of the butt as indicated at 3, thedifi'erence equaling the thickness of the sheet metal plate or disk 4which is applied thereto. Between these two diameters of the butt thereis provided a circumferential greet e5 adapted to receive the flange 6of the disk in the manner now to he err-- plained.

In practice the d hi 4: with its upstanding; marginal flange 6 n gpliedto the hut in a. single operation. through the medium of the die 7. Asshown in Fin. 3 the disk is laid in the die with its margin resting uponthe shoulder 8 of such die. The butt which is secured to any suitablepressure means as power press is forced directly downwardly with. theresult that the disk l: is turned and wrapped around the corners oi thebutt and the flange G is forced into the groove 5. It will be umlerstoodthat the die provided with a circular socket 9 into which the disk andthe lower end oi? the butt forced in this operation.

According to this construction. the butt is made very light and isprovided with durable end or cap and moreover such cap is so appliedthereto as to become practically an integral part 01" the butt. Moreoverthe steel. cap when worn out can be readiiyreplaced thereby prolongingthe life of the butt.

I claim:

1. A sand rammer butt comprising;- a body made oi? a light soft materialand a samarate end made of sheet metal.

2. A sand rammer butt comprising a body made of aluminum and a separateend of sheet metal secured to such body.

3. A. sand rammcr butt comprising a hol low body of aluminum having" at: ential groove near iss enter one rate end of sheet m t directedflange rec 4:. A. sand ramm which is cylindr.v cated conical at innermetal end applied to the cylimih end of such body.

A sand rammer butt coluprisimr a body which is cylindrical with itsextreme outer end reduced slightly in. diameter and which has acircumferential groove at the junction of the two diameters, and a diskof: sheet metal applied to the end oi such body and the reduced diameterthereof, said disk having a marginal flange received by said groove.
